ABSTRACT:
Separator materials suitable for use in electrolytic cells, for example, for the electrolysis of alkali metal chloride brines, are sealed by a method which comprises coating the sections to be sealed with a synthetic thermoplastic sealing agent and ultrasonically sealing the coated portions.
The method permits the sealing-in-place of separator materials and allows them to be unsealed and resealed without damage to the separators.
